Discrete Chain Link Oscillator

The following project will describe how to turn 5 discrete components into a building block which when serially connected will form an extendable flashing lighting chain.
Just a simple discrete solution without the aid of a microcontroller. Even so each block can have a different coloured LED and these can be assembled within the chain in any colour combination required.
Not a replacement for a Neopixel just different.

One set of components per block is required. Just multiply the component (5) by the number of blocks.
